Patented Feb. 5, 1935 I ofi ss' li'qn l iltfimti Fool) For; I v I 7 No Drawing; Application January 21, 1932, Serial No. 588,032. In Ja'panl'ebruary 6, 1931 Y My invention relates to improvements in procmulberry leaves or buds arelmilled to squeezethe ess for preparing food for silk worm to be used in place oflmulberryleaves the only. stufl for feed- -ing silk worm. The object of the inventionisflrstly to ec'onomize the cost of food, secondly to reduce the labour for feeding, thirdly to sparemulberrylfields, fourthly to increase the production of silk, iiithly to industrialize the selicultureand in summing up to economize the rate of production and reduce thecost of raw silk. 1

According to the present invention the chief matter of food containing proteid substance, fatty matter, fibrous matter, hydro-carbons free from nitrogen, ash and'water is obtained Irom'a suitable material, and appetizing agentflis .added thereto to prepare the food and silk worms are fed thereby in place of mulberry leaves.

said chief matter is made from soja-bean. Soja-bean iswashed and dipped in water about 50 hours. .When the hull-of thebean is soaked and the body is softened it is ground with plenty of water by the grinder and'the ground juice is boiled in a pan removing the 10am produced while I boiling. The boiled juice is then put in a canvas sack and milky juice is squeezed out by pressure. I

A caky matter containing proteid substance, fatty matter, fibrous matter, hydro-carbons tree from nitrogen, ash and water remains in the sack which is to be used as the chief matter. As for the appetizing agent some quantity of leaves or buds as the appetizen;v

juicewhich juice is poured on affore said caky substance'by an atomizer, The substance then is mixedand is put in a closed vessel for 2 hours or more and when the flavour ofitheappetizing I agent is quite absorbed on the chief matter it is scattered on the mat to feed thesilk worm, The

food is well adapted for the health of silk worm I I and excellent cocoons maybe obtained therefrom. Y b

The quantity of' appetizin'gagentt to thechief V matter is 5 percent'orsorne abouts. ,At the season when natural mulberry. leaves; or buds can 1 not be obtained mulberry twigs cut one-or two inches long are placed on sand in a hothouse or pit under a proper temperature and humidity 1'01 some 7 or 8 days to be quickly germinated and the buds are collected to be squeezed,which juice 9 is quite similar to those obtained frorn natural Havingnow particularly described and ascer clare that what 1, claim is:-
